GOVERNMENT SUPPORT

This invention was made with U.S. Government support under grants 5R01CA130876-05, 5P50CA090578-10, 5R01CA136851-04, 2R01CA136851-05, and 1R01CA172592-01A1 awarded by the National Cancer Institute. The U.S. Government has certain rights in the invention.

BACKGROUND OF THE INVENTION

Waldenström's macroglobulinemia (WM) is a distinct clinicopathological entity resulting from the accumulation, predominantly in the bone marrow, of clonally related lymphoplasmacytic cells which secrete a monoclonal IgM protein. This condition is considered to correspond to lymphoplasmacytic lymphoma (LPL) as defined by the World Health Organization classification system. WM is a rare disorder, with fewer than 1,500 cases occurring in the United States annually. There is a 2- to 3-fold risk increase of developing WM in people with a personal history of autoimmune diseases with autoantibodies and particularly elevated risks associated with hepatitis, human immunodeficiency virus, and rickettsiosis (Arch. Intern. Med., 2008, 168(17), 1903-9). There is no single accepted treatment for WM, and there can be a marked variation in clinical outcome. Objective response rates are high (>80%) but complete response rates are low (0-15%) (Clin. Adv. Hematol. Oncol., 2009, 7(10), 677-81, 687-90). Thus, there is a need for effective treatment of WM.

SUMMARY OF THE INVENTION

The present invention is based, at least in part, on the discovery of compounds of the Formula (A):

or a pharmaceutically acceptable salt thereof, wherein Q, U, R^(A), R^(B), R^(X), k, and l are defined herein, for the treatment of Waldenström's macroglobulinemia. The activity of these compounds was established by in vitro screening against several kinases (e.g., BTK, HCK, TAK1, HPK1).

In certain embodiments, compounds of Formula (A) are of formula:

and pharmaceutically acceptable salts thereof.

Another aspect of the invention relates to the compound of Formula (I-11):

and pharmaceutically acceptable salts thereof.

The present invention also provides compounds of Formula (II) or (V):

and pharmaceutically acceptable salts thereof, wherein Ring A′, Ring C′, Cy, X′, Y′, Z′, Q′, U′, R^(A)′, R^(B)′, R^(D)′, R^(X)′, k′, l′, and m′ are as defined herein.

The present invention is also based, at least in part, on the discovery that Waldenström's macroglobulinemia may be treated by administration of a compound of the invention to a subject in need thereof. The activity of these compounds was established by in vitro screening against several kinases (e.g., BTK, HCK, TAK1, HPK1) that are involved in the regulation of aberrant cell growth, as well as cell-based screening against several cell lines (e.g., BCWM.1, MWCL-1) that are disease state models of Waldenström's macroglobulinemia (Ditzel et al. Exp Hematol. 2007 September; 35(9):1366-75; Hodge et al. Blood. 2011 May 12; 117(19)).

The methods of treatment utilizing a compound of the invention also apply to B cell neoplasms of the group consisting of Hodgkin's lymphomas and most non-Hodgkin's lymphomas, such as diffuse large B cell lymphoma, Follicular lymphoma, mucosa-associated lymphatic tissue lymphoma (MALT), small cell lymphocytic lymphoma (overlaps with chronic lymphocytic leukemia), mantle cell lymphoma (MCL), Burkitt lymphoma, mediastinal large B cell lymphoma, nodal marginal zone B cell lymphoma (NMZL), splenic marginal zone lymphoma (SMZL), Intravascular large B-cell lymphoma, Primary effusion lymphoma, and Lymphomatoid granulomatosis.

The present invention is also based, at least in part, on pharmaceutical compositions comprising a compound of the invention (e.g., a compound of Formula (A), (I-11), (II), or (V) (e.g., compounds of Formula (A-1)-(A-18))) and a pharmaceutically acceptable excipient. In certain embodiments, the pharmaceutical composition may be useful for modulating the activity of a kinase in vitro or in a subject in need thereof, and/or for treating and/or preventing in a subject in need thereof a condition associated with aberrant activity of a kinase (e.g., a proliferative disease). In certain embodiments, the pharmaceutical composition may be useful for treatment of Waldenström's macroglobulinemia in a subject in need thereof.

The present invention also provides kits comprising a container with a compound of the invention (e.g., a compound of Formula (A), (I-11), (II), or (V) (e.g., compounds of Formula (A-1)-(A-18))), or a pharmaceutical composition thereof. The kits may include a single dose or multiple doses of a compound described herein or a pharmaceutical composition thereof. The kits may be useful for modulating the activity of a kinase in a subject in need thereof. The kits may also be useful for treating and/or preventing in a subject in need thereof a condition associated with aberrant activity of a kinase. In certain embodiments, the kits further include instructions for using the kit (e.g., for administering a compound described herein, or a pharmaceutical composition thereof).

The details of particular embodiments of the invention are set forth herein. Other features, objects, and advantages of the invention will be apparent from the Detailed Description, the Figures, the Examples, and the Claims.

Optionally substituted refers to a group which may be substituted or unsubstituted (e.g., “substituted” or “unsubstituted” alkyl, “substituted” or “unsubstituted” alkenyl, “substituted” or “unsubstituted” alkynyl, “substituted” or “unsubstituted” heteroalkyl, “substituted” or “unsubstituted” heteroalkenyl, “substituted” or “unsubstituted” heteroalkynyl, “substituted” or “unsubstituted” carbocyclyl, “substituted” or “unsubstituted” heterocyclyl, “substituted” or “unsubstituted” aryl or “substituted” or “unsubstituted” heteroaryl group). In general, the term “substituted” means that at least one hydrogen present on a group is replaced with a permissible substituent, e.g., a substituent which upon substitution results in a stable compound, e.g., a compound which does not spontaneously undergo transformation such as by rearrangement, cyclization, elimination, or other reaction. Unless otherwise indicated, a “substituted” group has a substituent at one or more substitutable positions of the group, and when more than one position in any given structure is substituted, the substituent is either the same or different at each position. The term “substituted” is contemplated to include substitution with all permissible substituents of organic compounds, and includes any of the substituents described herein that results in the formation of a stable compound. The present invention contemplates any and all such combinations in order to arrive at a stable compound. For purposes of this invention, heteroatoms such as nitrogen may have hydrogen substituents and/or any suitable substituent as described herein which satisfy the valencies of the heteroatoms and results in the formation of a stable moiety.

As used herein, a “leaving group”, or “LG”, is a term understood in the art to refer to a molecular fragment that departs with a pair of electrons upon heterolytic bond cleavage, wherein the molecular fragment is an anion or neutral molecule. See, for example, Smith, March Advanced Organic Chemistry 6th ed. (501-502). Examples of suitable leaving groups include, but are not limited to, halides (such as chloride, bromide, or iodide), alkoxycarbonyloxy, aryloxycarbonyloxy, alkanesulfonyloxy, arenesulfonyloxy, alkyl-carbonyloxy (e.g., acetoxy), arylcarbonyloxy, aryloxy, methoxy, N,O-dimethylhydroxylamino, pixyl, haloformates, —NO₂, trialkylammonium, and aryliodonium salts. In certain embodiments, the leaving group is a sulfonic acid ester. In certain embodiments, the sulfonic acid ester comprises the formula —OSO₂R^(LG1) wherein R^(LG1) is selected from the group consisting alkyl optionally, alkenyl optionally substituted, heteroalkyl optionally substituted, aryl optionally substituted, heteroaryl optionally substituted, arylalkyl optionally substituted, and heterarylalkyl optionally substituted. In certain embodiments, R^(LG1) is substituted or unsubstituted C₁-C₆ alkyl. In certain embodiments, R^(LG1) is methyl. In certain embodiments, R^(LG1) is —CF₃. In certain embodiments, R^(LG1) is substituted or unsubstituted aryl. In certain embodiments, R^(LG1) is substituted or unsubstituted phenyl. In certain embodiments R^(LG1) is:

In some cases, the leaving group is toluenesulfonate (tosylate, Ts), methanesulfonate (mesylate, Ms), p-bromobenzenesulfonyl (brosylate, Bs), or trifluoromethanesulfonate (triflate, Tf). In some cases, the leaving group is a brosylate (p-bromobenzenesulfonyl). In some cases, the leaving group is a nosylate (2-nitrobenzenesulfonyl). In certain embodiments, the leaving group is a sulfonate-containing group. In certain embodiments, the leaving group is a tosylate group. The leaving group may also be a phosphineoxide (e.g., formed during a Mitsunobu reaction) or an internal leaving group such as an epoxide or cyclic sulfate.

These and other exemplary substituents are described in more detail in the Detailed Description, Figures, Examples, and Claims. The invention is not intended to be limited in any manner by the above exemplary listing of substituents.

OTHER DEFINITIONS

The following definitions are more general terms used throughout the present application.

As used herein, the term “pharmaceutically acceptable salt” refers to those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response, and the like, and are commensurate with a reasonable benefit/risk ratio. Pharmaceutically acceptable salts are well known in the art. For example, Berge et al. describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 1977, 66, 1-19, incorporated herein by reference. Pharmaceutically acceptable salts of the compounds of this invention include those derived from suitable inorganic and organic acids and bases. Examples of pharmaceutically acceptable, nontoxic acid addition salts are salts of an amino group formed with inorganic acids, such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid, and perchloric acid or with organic acids, such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid, or malonic acid or by using other methods known in the art such as ion exchange. Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, picrate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate, undecanoate, valerate salts, and the like. Salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium, and N⁺(C₁ alkyl)₄ ⁻ salts. Representative alkali or alkaline earth metal salts include sodium, lithium, potassium, calcium, magnesium, and the like. Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, lower alkyl sulfonate, and aryl sulfonate.

The term “solvate” refers to forms of the compound, or a salt thereof, that are associated with a solvent, usually by a solvolysis reaction. This physical association may include hydrogen bonding. Conventional solvents include water, methanol, ethanol, acetic acid, DMSO, THF, diethyl ether, and the like. Compounds of the invention may be prepared, e.g., in crystalline form, and may be solvated. Suitable solvates include pharmaceutically acceptable solvates and further include both stoichiometric solvates and non-stoichiometric solvates. In certain instances, the solvate will be capable of isolation, for example, when one or more solvent molecules are incorporated in the crystal lattice of a crystalline solid. “Solvate” encompasses both solution-phase and isolable solvates. Representative solvates include hydrates, ethanolates, and methanolates.

The term “hydrate” refers to a compound that is associated with water. Typically, the number of the water molecules contained in a hydrate of a compound is in a definite ratio to the number of the compound molecules in the hydrate. Therefore, a hydrate of a compound may be represented, for example, by the general formula R.x H₂O, wherein R is the compound and wherein x is a number greater than 0. A given compound may form more than one type of hydrates, including, e.g., monohydrates (x is 1), lower hydrates (x is a number greater than 0 and smaller than 1, e.g., hemihydrates (R.0.5H₂O)), and polyhydrates (x is a number greater than 1, e.g., dihydrates (R.2H₂O) and hexahydrates (R.6H₂O)).

The term “tautomers” refer to compounds that are interchangeable forms of a particular compound structure, and that vary in the displacement of hydrogen atoms and electrons. Thus, two structures may be in equilibrium through the movement of π electrons and an atom (usually H). For example, enols and ketones are tautomers because they are rapidly interconverted by treatment with either acid or base. Another example of tautomerism is the aci- and nitro-forms of phenylnitromethane, that are likewise formed by treatment with acid or base. Tautomeric forms may be relevant to the attainment of the optimal chemical reactivity and biological activity of a compound of interest.

It is also to be understood that compounds that have the same molecular formula but differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space are termed “isomers.” Isomers that differ in the arrangement of their atoms in space are termed “stereoisomers”.

Stereoisomers that are not mirror images of one another are termed “diastereomers” and those that are non-superimposable mirror images of each other are termed “enantiomers”. When a compound has an asymmetric center, for example, it is bonded to four different groups, a pair of enantiomers is possible. An enantiomer can be characterized by the absolute configuration of its asymmetric center and is described by the R- and S-sequencing rules of Cahn and Prelog, or by the manner in which the molecule rotates the plane of polarized light and designated as dextrorotatory or levorotatory (i.e., as (+) or (−)-isomers respectively). A chiral compound can exist as either individual enantiomer or as a mixture thereof. A mixture containing equal proportions of the enantiomers is called a “racemic mixture”.

The term “polymorphs” refers to a crystalline form of a compound (or a salt, hydrate, or solvate thereof). All polymorphs have the same elemental composition. Different crystalline forms usually have different X-ray diffraction patterns, infrared spectra, melting points, density, hardness, crystal shape, optical and electrical properties, stability, and solubility. Recrystallization solvent, rate of crystallization, storage temperature, and other factors may cause one crystal form to dominate. Various polymorphs of a compound can be prepared by crystallization under different conditions.

The term “prodrugs” refers to compounds that have cleavable groups and become by solvolysis or under physiological conditions the compounds of the invention, which are pharmaceutically active in vivo. Such examples include, but are not limited to, choline ester derivatives and the like, N-alkylmorpholine esters and the like. Other derivatives of the compounds of this invention have activity in both their acid and acid derivative forms, but in the acid sensitive form often offers advantages of solubility, tissue compatibility, or delayed release in the mammalian organism (see, Bundgard, H., Design of Prodrugs, pp. 7-9, 21-24, Elsevier, Amsterdam 1985). Prodrugs include acid derivatives well known to practitioners of the art, such as, for example, esters prepared by reaction of the parent acid with a suitable alcohol, or amides prepared by reaction of the parent acid compound with a substituted or unsubstituted amine, or acid anhydrides, or mixed anhydrides. Simple aliphatic or aromatic esters, amides and anhydrides derived from acidic groups pendant on the compounds of this invention are particular prodrugs. In some cases it is desirable to prepare double ester type prodrugs such as (acyloxy)alkyl esters or ((alkoxycarbonyl)oxy)alkylesters. Particularly the C₁-C₈ alkyl, C₂-C₈ alkenyl, C₂-C₈ alkynyl, aryl, C₇-C₁₂ substituted aryl, and C₇-C₁₂ arylalkyl esters of the compounds of the invention (e.g., the compounds of Formula (A), (I-11), (II), or (V)).

BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

In an effort to identify novel treatments for Waldenström's macroglobulinemia, in vitro screens were carried out against several kinases (e.g., BTK, HCK, TAK1, HPK1). These kinases are involved in the regulation of aberrant cell growth associated with this condition. Cell-based screening was also carried out in several disease state model lines of Waldenström's macroglobulinemia (e.g., BCWM.1, MWCL-1). Based on these screening efforts and subsequent lead optimization, compounds of any one of Formulae (A), (I-11), (II), and (V) (e.g., compounds of Formula (A-1)-(A-18)) were identified.

Also provided are methods to treat other B cell neoplasms using compounds of the invention in combination with inhibitors of Bruton's tyrosine kinase (BTK), interleukin-1 receptor-associated kinase 1 (IRAK1), interleukin-1 receptor-associated kinase 4 (IRAK4), bone marrow on X chromosome kinase (BMX), phosphoinositide 3-kinase (PI3K), transforming growth factor b-activated kinase-1 (TAK1), and/or a Src family kinase. In certain embodiments, one or more compounds of the invention are used in combination with an inhibitor of the phosphoinositide 3-kinase delta isoform (PI3Kδ). In certain embodiments, combinations of 2, 3, 4, 5, 6, 7, 8, 9, 10, or more of the agents described herein are used for treating WM. In certain embodiments, the agents described herein are used in combination with kinase inhibitors such as inhibitors of Bruton's tyrosine kinase (BTK), interleukin-1 receptor-associated kinase 1 (IRAK1), interleukin-1 receptor-associated kinase 4 (IRAK4), bone marrow on X chromosome kinase (BMX), and/or phosphoinositide 3-kinase (PI3K), transforming growth factor b-activated kinase-1 (TAK1), and/or a Src family kinase.

Waldenstrom's macroglobulinemia (WM) is a distinct clinicopathological entity resulting from the accumulation, predominantly in the bone marrow, of clonally related lymphoplasmacytic cells which secrete a monoclonal IgM protein. This condition is considered to correspond to lymphoplasmacytic lymphoma (LPL) as defined by the World Health Organization classification system. Genetic factors play an important role in the pathogenesis of WM, with 25% of patients demonstrating a family history. IgM monoclonal gammopathy of unknown significance (MGUS) often precedes the development of WM.

As used herein, a B cell neoplasm includes both Hodgkin's lymphoma and non-Hodgkin's lymphomas. Classical Hodgkin's lymphoma (HL) includes various subtypes such as Nodular sclerosing HL, Mixed-cellularity subtype, Lymphocyte-rich or Lymphocytic predominance and Lymphocyte depleted. Examples of B cell non-Hodgkin's lymphomas include, but are not limited to, Waldenström's macroglobulinemia, diffuse large B cell lymphoma, follicular lymphoma, mucosa-associated lymphatic tissue lymphoma (MALT), small cell lymphocytic lymphoma (overlaps with chronic lymphocytic leukemia), mantle cell lymphoma (MCL), Burkitt lymphoma, mediastinal large B cell lymphoma, nodal marginal zone B cell lymphoma (NMZL), splenic marginal zone lymphoma (SMZL), intravascular large B-cell lymphoma, primary effusion lymphoma, and lymphomatoid granulomatosis.

In certain embodiments, compounds of the present invention include those which:

-   -   exhibit kinase inhibitory activity,     -   exhibit the ability to inhibit transforming growth factor         b-activated kinase-1 (TAK1), hemopoietic cell kinase (HCK) or         both TAK1 and HCK,     -   exhibit the ability to inhibit hematopoietic progenitor kinase 1         (HPK1, also known as mitogen-activated protein kinase kinase         kinase kinase 1 or MAP4K1),     -   exhibit the ability to inhibit Bruton's tyrosine kinase (BTK),         v-src sarcoma (Schmidt-Ruppin A-2) viral oncogene homolog (SRC)         family of kinases or both BTK and SRC,     -   exhibit cytotoxic or growth inhibitory effect on WM cell lines         maintained in vitro or in animal studies using a scientifically         acceptable cancer cell xenograft model; and/or     -   exhibit a therapeutic profile (e.g., optimum safety and curative         effect) that is superior to existing chemotherapeutic agents.

As used herein “kinase” refers to a large class of enzymes which catalyze the transfer of the γ-phosphate from ATP to the hydroxyl group on the side chain of Ser/Thr or Tyr in proteins and peptides and are intimately involved in the control of various important cell functions, perhaps most notably: signal transduction, differentiation and proliferation. There are estimated to be about 2,000 distinct protein kinases in the human body and although each of these phosphorylates particular protein/peptide substrates, they all bind the same second substrate ATP in a highly conserved pocket. About 50% of the known oncogene products are protein tyrosine kinases PTKs and their kinase activity has been shown to lead to cell transformation.

In certain embodiments, the kinase to be inhibited is involved in the myeloid differentiation primary response gene (88) (MYD88) signaling pathway. For example, the kinase is Transforming growth factor b-activated kinase-1 (TAK1) or Hemopoietic cell kinase (HCK). In certain embodiments, the compound of the invention inhibits TAK1, HCK, or both TAK1 and HCK.

Myeloid differentiation primary response gene (88) (MYD88) L265P is a widely expressed somatic mutation in WM patients that supports NF-NFκB signaling through stimulation of BTK, IRAK1/4, TAK1. MYD88 is an adaptor molecule for Toll-like receptors (TLR) with the exception of TLR-3 and interleukin-1 receptor (IL-1R) signaling. Following TLR or IL-1R stimulation, MYD88 is recruited to the activated receptor complex as a homodimer which then complexes with interleukin-1 receptor-associated kinase 4 (IRAK4) and activates IRAK1 and IRAK2. Tumor necrosis factor receptor associated factor 6 (TRAF6) is then activated by IRAK1 leading to NFκB activation via IκBα phosphorylation and TAK1 activation.

Transforming growth factor b-activated kinase-1 (TAK1; also known as MAP3K7) is a member of the serine/threonine protein kinase family. This kinase mediates the signaling transduction induced by TGF beta and morphogenetic protein (BMP), and controls a variety of cell functions including transcription regulation and apoptosis. TAK1 knockout is embryonic lethal to mice. Conditional knock-down of TAK1 in adult mice results in systemic inflammation, spenomegaly, degeneration in heart, kidneys and liver and increased proliferation and differentiation of myeloid progenitor cells. TAK1 is located downstream of Myd88, Bruton's tyrosine kinase (BTK), and interleukin-1 receptor-associated kinase (IRAK), and is being investigated for its role in innate immunity, inflammatory response, and Ras-dependent cancers.

Hemopoietic cell kinase (HCK) is a non-receptor tyrosine-protein kinase found in hematopoietic cells and is known to interact with Bruton's tyrosine kinase (BTK) upon activation by B cell receptors (Proc. Natl. Acad. Sci. USA. 1994, 91(17), 8152-55). HCK transmits signals from cell surface receptors and plays an important role in the regulation of innate immune responses, including neutrophil, monocyte, macrophage and mast cell functions, phagocytosis, cell survival and proliferation, cell adhesion and migration. It acts downstream of receptors that bind the Fc region of immunoglobulins, such as FCGR1A and FCGR2A, but also CSF3R, PLAUR, the receptors for IFNG, IL2, IL6 and IL8, and integrins, such as ITGB1 and ITGB2. During the phagocytic process, it mediates mobilization of secretory lysosomes, degranulation, and activation of NADPH oxidase to bring about the respiratory burst. It also plays a role in the release of inflammatory molecules, promotes reorganization of the actin cytoskeleton and actin polymerization, and formation of podosomes and cell protrusions.

Hematopoietic progenitor kinase 1 (HPK1) is a hematopoietic cell-restricted member of the Ste20 serine/threonine kinase super family. HPK1 is also known as mitogen-activated protein kinase kinase kinase kinase 1 (MAP4K1). HPK1 is a tissue-specific upstream activator of the MEKK/JNK/SAPK signaling pathway. HPK1 diminishes T cell receptor (TCR) signaling activity and T cell proliferation by phosphorylating the adaptor protein SLP-76. Cytosolic HPK1 is recruited to the TCR complex, and its kinase activity is induced upon the engagement of the TCR. Overexpression of HPK1 suppresses TCR-induced activation of AP-1-dependent gene transcription in a kinase-dependent manner, suggesting that the kinase activity of HPK1 is required to inhibit the Erk MAPK pathway. This blockage of the Erk MAPK pathway is thought to be the inhibitory mechanism that negatively regulates TCR-induced IL-2 gene transcription (Immunol. Res. 2012, 54(1-3), 262-65). In certain embodiments, the compounds of the invention, such as the compounds of Formula (A), (I-11), (II), or (V) (e.g., compounds of Formula (A-1)-(A-18)), inhibit HPK1.

In certain embodiments, the compounds of the invention are selective inhibitors of TAK1, HCK, or HPK1. The term “selective inhibitor” as used herein is understood to mean that in contrast to many kinase inhibitors of the prior art, the compounds do not act on a variety of kinases but act specifically on TAK1, HCK, or HPK1. In certain embodiments, the compounds of the invention inhibit one or more kinases in addition to TAK1, HCK, or HPK1 such as BTK or the SRC family of kinases. In certain embodiments of the invention, the specificity of the inhibitors is given by the IC₅₀ value. In some embodiments, the IC₅₀ value for a selective inhibitor is <100 μM for TAK1, HCK, or HPK1, but >100 μM for other kinases.

The IC₅₀ value is defined as the concentration of inhibitor required to inhibit 50% of the kinase activity. In certain embodiments, the compounds of the invention may exhibit IC₅₀ values <100 μM. In certain other embodiments, the compounds exhibit IC₅₀ values <50 μM. In certain other embodiments, the compounds exhibit IC₅₀ values <40 μM. In certain other embodiments, the compounds exhibit IC₅₀ values <30 μM. In certain other embodiments, the compounds exhibit IC₅₀ values <20 μM. In certain other embodiments, the compounds exhibit IC₅₀ values <10 μM. In certain other embodiments, the compounds exhibit IC₅₀ values <7.5 μM. In certain embodiments, the compounds exhibit IC₅₀ values <5 μM. In certain other embodiments, the compounds exhibit IC₅₀ values <2.5 μM. In certain embodiments, the compounds exhibit IC₅₀ values <1 μM. In certain embodiments, the compounds exhibit IC₅₀ values <0.75 μM. In certain embodiments, the compounds exhibit IC₅₀ values <0.5 μM. In certain embodiments, the compounds exhibit IC₅₀ values <0.25 μM. In certain embodiments, the compounds exhibit IC₅₀ values <0.1 μM. In certain other embodiments, the compounds exhibit IC₅₀ values <75 nM. In certain other embodiments, the compounds exhibit IC₅₀ values <50 nM. In certain other embodiments, the compounds exhibit IC₅₀ values <25 nM. In certain other embodiments, the compounds exhibit IC₅₀ values <10 nM. In other embodiments, the compounds exhibit IC₅₀ values <7.5 nM. In other embodiments, the compounds exhibit IC₅₀ values <5 nM.

In certain embodiments, the compounds of the invention (e.g., the compounds of Formula (A), (I-11), (II), or (V)) inhibit HCK selectively. In certain embodiments, the compounds of the invention (e.g., the compounds of Formula (A), (I-11), (II), or (V)) inhibit TAK1 selectively. A non-limiting example of a selective TAK1 inhibitor is:

In certain embodiments, the compounds of the invention (e.g., the compounds of Formula (A), (I-11), (II), or (V)) inhibit both TAK1 and HCK. A non-limiting example of a dual TAK1/HCK inhibitor is:

Also, provided are methods to treat B cell neoplasms using compounds of the invention in combination with inhibitors of Bruton's tyrosine kinase (BTK), interleukin-1 receptor-associated kinase 1 (IRAK1), interleukin-1 receptor-associated kinase 4 (IRAK4), bone marrow on X chromosome kinase (BMX), phosphoinositide 3-kinase (PI3K), transforming growth factor b-activated kinase-1 (TAK1), and/or a Src family kinase. In certain embodiments, one or more compounds of the invention are used in combination with an inhibitor of the phosphoinositide 3-kinase delta isoform (PI3Kδ). In certain embodiments, combinations of 2, 3, 4, 5, 6, 7, 8, 9, 10, or more of the agents described herein are used for treating WM. In certain embodiments, the agents described herein are used in combination with inhibitors of Bruton's tyrosine kinase (BTK), interleukin-1 receptor-associated kinase 1 (IRAK1), interleukin-1 receptor-associated kinase 4 (IRAK4), bone marrow on X chromosome kinase (BMX), phosphoinositide 3-kinase (PI3K), transforming growth factor b-activated kinase-1 (TAK1), and/or a Src family kinase.

Bruton's tyrosine kinase (BTK) is a key signaling enzyme expressed in all hematopoietic cells types except T lymphocytes and natural killer cells. BTK plays an essential role in the B cell signaling pathway linking cell surface B cell receptor BCR stimulation to downstream intracellular responses. BTK is a key regulator of B cell development activation signaling and survival (Kurosaki, Curr. Op. Imm., 2000, 276-281; Schaeffer and Schwartzberg, Curr. Op. Imm., 2000, 282-288). In addition BTK plays a role in a number of other hematopoietic cell signaling pathways, e.g., Toll like receptor (TLR) and cytokine receptor-mediated TNF-α production in macrophages, IgE receptor (FcepsilonRI) signaling in mast cells, inhibition of Fas/APO-1 apoptotic signaling in B-lineage lymphoid cells, and collagen stimulated platelet aggregation. See e.g., C. A. Jeffries, et al., J. Biol. Chem., 2003, 278, 26258-26264; N. J. Horwood, et al., J. Exp. Med., 2003, 197, 1603-1611; Iwaki et al., J. Biol. Chem., 2005, 280(48), 40261-40270; Vassilev et al., J. Biol. Chem., 1999, 274(3), 1646-1656; and Quek et al., Curr. Biol., 1998, 8(20), 1137-1140. Activated Btk interacts with MyD88 and TRIF, promoting the activation of MyD88-dependent and TRIF-dependent pathways (Nature Immunology, 2011, 12, 416-424).

BTK inhibitors are well-known in the art, and include, for example, ibrutinib and benzonaphthyridinones (see U.S. provisional patent application U.S. Ser. No. 61/716,273, filed Oct. 19, 2012). Additional non-limiting examples of BTK inhibitors are disclosed in WO 1999/054286, WO 2013/010380, WO 2009/137596, WO 2011/029043, WO 2010/056875, WO 2000/056737, and WO 2013/067277.

IRAK1 and 4 are serine/threonine-protein kinases that play a critical role in initiating innate immune response against foreign pathogens. They are involved in Toll-like receptor (TLR) and IL-1R signaling pathways, and are rapidly recruited by MYD88 to the receptor-signaling complex upon TLR activation. Association with MYD88 leads to IRAK1 phosphorylation by IRAK4 and subsequent autophosphorylation and kinase activation of IRAK1 (Immunity, 1997, 7(6), 837-47). IRAK4−/− mice have abolished cellular responses to various IL-1 and TLR ligands and are severely impaired in their response to viral and bacterial challenges. IRAK1−/− mice show a similar but partial response.

IRAK1 and IRAK4 inhibitors are well-known in the art, and include, for example, those disclosed in WO 2003/030902, WO 2012/007375, G. M. Buckely et al., Biorg. Med. Chem. Lett., 2008, 18, 3211-3214, and G. M. Buckely et al., Biorg. Med. Chem. Lett., 2008, 18, 3656-3660, WO2013/074986, and U.S. provisional patent application, U.S. Ser. No. 61/727,640, filed Nov. 16, 2012.

In certain embodiments, the IRAK4 inhibitor is of formula:

or an analog thereof.

“Bone Marrow on X chromosome” kinase (BMX, also termed ETK) is a non-receptor tyrosine kinase and is activated downstream of phosphatidylinositol-3 kinase (PI-3K) and v-src sarcoma (Schmidt-Ruppin A-2) viral oncogene homolog (SRC), but its substrates are unknown. Positional scanning peptide library screening revealed a marked preference for a priming phosphotyrosine (pY) in the −1 position. Potential substrates include multiple tyrosine kinases with kinase domain pYpY sites required for full activity. BMX has been found to phosphorylate residue Y577 of focal adhesion kinase (FAK) subsequent to Y576 phosphorylation by SRC. In addition, BMX loss by RNA interference and mouse embryonic fibroblasts (MEFs) from Bmx negative (Bmx⁻) mice displayed impaired FAK signaling. Insulin receptor (IR) phosphorylation similarly was decreased by BMX loss, as was hepatic IR phosphorylation in Bmx⁻ mice. However, glucose tolerance was increased, reflecting a marked compensatory decrease in the activity of the AKT phosphatase PHLPP. These findings reveal a mechanism through which BMX functions as a central regulator of multiple kinase pathways.

BMX inhibitors are well-known in the art, and include, for example, those disclosed in U.S. Ser. No. 61/716,273 and 61/717,345, the contents of both of which are incorporated herein by reference. In certain embodiments, the BMX inhibitor is of formula:

or an analog thereof.

Phosphatidylinositol 3-kinases (PI3-kinases or PI3Ks) are a family of enzymes involved in cellular functions such as cell growth, proliferation, differentiation, motility, survival and intracellular trafficking, which in turn are involved in cancer. PI3Ks are a family of related intracellular signal transducer enzymes capable of phosphorylating the 3 position hydroxyl group of the inositol ring of phosphatidylinositol (Ptdlns). Phosphatidylinositol 3-kinase is composed of an 85 kDa regulatory subunit and a 110 kDa catalytic subunit. The protein encoded by PI3KCA gene represents the catalytic subunit, which uses ATP to phosphorylate phosphatidylinositols (Ptdlns), Ptdlns4P and Ptdlns(4,5)P2. Of particular interest is the PI3K delta isoform, which is expressed in white blood cells and is mainly involved in the signaling, development, and survival of B cells.

PI3K inhibitors are well-known in the art, and include, for example, those disclosed in International PCT Publications WO 2013/088404, WO 2012/068096, and WO 2013/052699, which are incorporated herein by reference.

In certain embodiments, the PI3K inhibitor is

or its analogs.

The BTK inhibitors, the IRAK1 inhibitors, the IRAK4 inhibitors, and/or the PI3K inhibitors can be administered to the subject simultaneously or sequentially.

A “subject” or “patient” to which administration is contemplated includes, any animal. In some embodiments, a subject includes but is not limited to, humans, commercially relevant mammals such as cattle, pigs, horses, sheep, goats, cats, and/or dogs), birds (e.g., commercially relevant birds such as chickens, ducks, geese, and/or turkeys) and experimental animals (e.g., mice, rats, non-human primates). A subject in need of treatment is a subject identified as having a B cell neoplasm, i.e., the subject has been diagnosed by a physician (e.g., using methods well known in the art) as having a B cell neoplasm. In certain embodiments, the subject in need of treatment is a subject suspected of having or developing a B cell neoplasm, such as a subject presenting one or more symptoms indicative of a B cell neoplasm. The term “subject in need of treatment” further includes people who once had a B cell neoplasm but whose signs and/or symptoms have been ameliorated (i.e., their cancer is in remission). The one or more symptoms or clinical features of B cell neoplasms include, but are not limited to, asymptomatic localized or generalized peripheral lymphadenopathy, plasmacytic difference, bone marrow involvement, autoimmune thrombocytopenia, peripheral blood villous lymphocytes, end organ damage (hypercalcemia, renal insufficiency, bone lesions), recurrent infections, elevated creatine, hyperuricemia, and hypoalbunemia.

Kinome Scan

Compounds (A-2) and (A-17) were run in the Kinome Scan™ (DiscoverRx) assay to determine the inhibition against a broad panel of known kinases.

Results

Table 3 shows the KinomeScan (an active site-directed competition binding assay to measure interactions between test compounds and individual kinases) data of each compound, II-1 and I-13. Lower values indicate a greater inhibition for a given kinase by the test compound. As is shown, II-1 and I-13 inhibited several other kinases include LOK, DDR1, JNK2, ZAK, IKK-alpha, BLK, p38-alpha, ABL1, LYN, and STK36 along with the key target HCK.

Kinative

The kinase selectivity of compounds (A-5) and (A-14) were evaluated using a chemical proteomic approach named KiNativ which detects 260 kinases in A375 cells (ActivX Biosciences). To probe the intracellular targets of the compounds, A375 cells were incubated with the inhibitor at 1 μM final concentration and then looked for protection of labeling by an ATP-biotin probe that non-specifically labels conserved lysines on kinases and other nucleotide-dependent enzymes.

Results

Table 4 shows that compound (A-5) inhibits a number of kinases at 1 βM, including Ab1 (>90%), FYN (71.2%), LYN (87.8%), and ZAK (75.7%). Table 5 shows that compound (A-14) inhibits a number of kinases at 1 μM, including Ab1 (>90%), FYN (88.2%), LYN (85.7%), and ZAK (75.8%).

Example 3 p-BTK and p-Hck Inhibition Protocol for PhosFlow Studies

PhosFlow was performed to detect levels of phosphorylation for BTK-pY223 (BD Biosciences) and Hck-pY410 (Abcam) in BCWM.1 cells, in BCWM cells that stably overexpress HCK (BCWM.1_HCK-wt) and in BCWM.1 cells that stably overexpress the T338M mutant of HCK (BCWM.1_HCK-mu). Cells were fixed with BD Phosflow Fix Buffer I (BD Biosciences) at 37° C. for 10 min, then washed twice with BD Phosflow Perm/Wash Buffer I (BD Biosciences). Cells were suspended in BD Phosflow Perm/Wash Buffer I at 10 million/ml and antibodies aliquoted to flow tubes with 100 μl cells. Cells were incubated at room temperature for 30 min in the dark. Cells were washed twice with BD Phosflow Perm/Wash Buffer I before performing flow analysis using a BD™ FACSCanto II flow cytometer.

Protocol for Apoptosis Analysis

Apoptosis analysis of WM patient primary lymphoplasmacytic cells (LPCs) was preformed following A-5 and A-14 treatment of Bone marrow mononuclear cells (BMMC) from WM patients for 24 hours. Apoptosis analysis was performed using Annexin V/Propidium iodide staining with the Apoptosis Detection Kit I (BD Pharmingen) in CD19-APC-cy7 antibody (BD Pharmingen) gated LPCs population.

Results

PhosFlow studies indicate both A-5 and A-14 inhibit Hck and BTK phosphorylation in BCWM.1 cells and BCWM.1 cells with genetic engineered expression of Hck wild type (-wt) and T338M gatekeeper mutant (-mu) with both 0.5 μM and 0.1 μM doses (shown by Table 6 and Table 7, respectively). In addition, the expression of Hck-wt or Hck-mu increased the resistance to the inhibition of both Hck and BTK phosphorylations by A-5 and A-14, with more resistance presented in Hck-mu expressing BCWM.1 cells. Both A-5 and A-14 induced significant apoptosis in WM patient primary LPCs compared with DMSO control, as shown in Table 8.
